Lindsay Lohan has been sued by a nanny who claims LiLo creamed her in a Maserati.
The accident occurred in September, 2010. TMZ broke the story ... a witness claimed he saw Lindsay run a red light in her sports car in West Hollywood, hitting a nanny who was pushing a stroller across the intersection.
The witness claimed 3 of the 4 wheels on the stroller became airborne. The child wasn't injured but the nanny -- Nubia Del Carmen Preza -- claims she was, and that's why she is suing.
And get this ... the witness told us, "She was in shock and Hispanic so she was scared."
